I'm not sure I think this is the right solution to this.  Now the  
student can test for equivalence of answer without submitting.  I  
think of preview mode as not giving any information except how the  
expression has been parsed.  It should only give information about  
how the answer is being interpretted, not anything else about the  
answer (in my opinion).  Being told that it is the same as the  
previous answer is information about the meaning and the value of the  
answer, and I don't think that belongs in preview mode.

The lines you changed had already fixed bug 752 in the sense that  
they did not give the message in preview mode regardless of the  
correctness.  So this "attack" on the problem is already blocked by  
the old version.

Just a thought.
